So since the Ring spent a lot of time at the bottom of that river, it's safe to say that the occasional creature other than the human-like races came into contact with it. (Catfish, crayfish, etc.)

The Bunny: The Ring as Jonah, as in the guy swallowed by a whale and spit out on a distant shore. The exact location of the Ring when Deagol and Smeagol found it wasn't known, so how did it get from that stretch of River where Isildur died to wherever Smeagol came to steal it?

Catfish will try to eat just about anything...
